The NVIDIA® Tesla™ C2050 / Tesla C2070 computing processor board is a PCI Express 2.0 full-height (4.376 inches by 9.75 inches) form factor computing add-in card based on the NVIDIA Tesla T20 graphics processing unit (GPU). This board is targeted as high-performance computing (HPC) solution for PCI Express systems. The Tesla C2050 / Tesla C2070 is capable of running 515 GFLOPs/sec of double precision processing performance. Tesla C2050 comes standard with 3 GB of GDDR5 memory at 144 GB/s bandwidth. Tesla C2070 comes standard with 6 GB of GDDR5 memory. Both the Tesla C2050 and Tesla C2070 can be configured by the end user to enable or disable ECC or error correcting codes that can fix single-bit errors and report double-bit errors. Enabling ECC will cause some of the memory to be used for the ECC bits so the user available memory will decrease to 2.625 GB for Tesla C2050 and 5.25 GB for Tesla C2070.
